Composition of 10RP 8.5/3 pigment and practicality color block prepared by the same

Abstract

The invention discloses a compound of a 10RP 8.5 / 3 coating, and a method for preparing real color lumps with the compound. The compound consists of CSC-A base material in an amount of 995 to 1005 parts; PR122 coating in an amount of 0.62 to 0.7 parts and accounting for 30 percent; PR101 coating in an amount of 1 to 1.21 parts and accounting for 65 percent. The essential component of the CSC-A base material is an acrylic acid copolymer which accounts for 30 to 40 percent. TiO2 is used as a primary white coating and accounts for 18 to 22 percent. The contrast ratio of the base material is 0.90 to 0.96; the Stormer viscosity is 90KU to 100KU; when the incident angle is 85 degrees, the glossiness is 5 to 10. The compound has high weatherability and stability, and the proportion of the compound can be reproduced well. The raw materials used and the technological process meet the requirement and standard of low and zero VOC, and environmental protection. The colors of the real color lumps are not or seldom different from the standard values in the theoretical models in the China Color System, and the colors achieved are very accurate. In addition, the manufacturing process is refined, and is valuable for application.

Description

【Technical field】 [0001] The invention relates to a composition, in particular to a pigment composition, and a physical color block prepared by using the composition. 【Background technique】 [0002] A color includes hue, lightness and chroma. As long as the hue, lightness and chroma are determined, a unique color can be determined. The Chinese color system GB / T15608-1995 stipulates that in the theoretical model of the Chinese color system, any color can be calibrated by the hue, lightness and chroma on the color plane, and given a certain label. The calibration method is to first write the hue H, then write the lightness V, write the chroma C after the slash, expressed as H V / C, take the color 10BG 5.5 / 6 as an example, 10BG means the hue, 5.5 means the lightness, and 6 means the color Spend. [0003] From the theoretical value in the theoretical model to the production process of the actual color block, many important links such as color difference ΔE, raw materials, formu...
